            <p>#漏洞</p>
<p>1.网络协议本身的逻辑漏洞<br>2.通过网络分析工具，窃取<br>3.应用场景中网络协议的不同逻辑错误<br>4.基主机，操作系统，通信层，应用层</p>
<p>协议：<br>ARP协议：根据IP获取物理地址，无法在对等网络中解析数据包的来源</p>
<p>ARP欺骗：<br>通过MAC地址与目标IP相关联。以便于攻击者可以接收到与目标的任何？</p>
<p>2.DNS<br> 可将域名解析为IP<br> 缓存中毒，DNS欺骗</p>
<p>3.IP协议<br>  根据端到端的设计原则，IP为主机提供一种无连接、不可靠、尽力而为的数据包传输服务。<br>  吧发送的IP包中的源IP地址 改成被新人的友好主机的IP地址，进而实施攻击。</p>
<p>4.远程桌面协议 RDP<br>  RDP漏洞攻击，不用任何交互绕过认证，直接通过RDP协议进行连接，进而发送恶意代码。</p>
<p>5.简单邮件传输协议（SMTP）<br>通过电子邮件，发送垃圾软件和电子邮件。执行目录攻击，收集有效电子邮件。<br>根据漏洞进行缓冲区溢出攻击，特洛伊木马攻击和shell脚本攻击等，还可利用电子邮件发送垃圾邮件或恶意软件。</p>
<p>#软件和硬件的漏洞</p>
<p>1.软件<br>系统软件<br>应用软件<br>数据库软件</p>
<p>软件错误，软件缺陷，软件失效</p>
<ol start="2">
<li>硬件，通过通信线路传输，传输过程中也可能被截取</li>
<li>电磁波辐射中的信息也可能被接受<br>4.水电，空调，中断，会影响系统运行</li>
</ol>
